General Description
JJC' s SIDAC (Silicon Diode for Alternating Current)
represents an unique set of thyristor qualities. The SIDAC
is a bidirectional voltage triggered switch. Upon application
of a voltage exceeding the sidac breakover voltage point,
the sidac switches on through a negative resistance region
to a low on-state voltage. conduction will continue until the
current is interrupted or drops below the minimum holding
current of the device.
At present, JINGHENG can offer three kinds of package in
DO-41,R-1,Mini-MELF,SMA,SOD-123FL
JINGHENG's sidacs feature glass passivated junctions to ensure
a rugged and dependable device capable of withstanding
harsh environments.

NOTE A: Input pulse width is increased until ICM=0.63A.
NOTE B: Sidac (or Diac or series of diacs) chosen so that VBO is just below VCEO rating of transistor to be protected. The Sidac (or Diac) eliminates a reverse breakdown
of the transistor in inductive switching circuits where otherwise the transistor could be destroyed.
